DOOR HOLDER AND STOP.

Specification of Letters Patent.

Patented Sept. 16, 1913.

To all whom it may concern:

Be it known that I, MICHAEL J. KENNY, a citizen oft-he United States,and a resident of the city of Chicago, county of Cook, and State ofIllinois, have invented certain new and useful Improvements in DoorHolders and Stops, of which the following is a specification.

My ihvention relates to imprm-en'ients in door holders and stops and hasfor its object the production of a device of this character which willbe of improved construction and cflicient in use.

Other objects will appear hereinafter.

The invention consists in the combinations andarrangements of partshereinafter described and claimed. I y

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which,

Figure 1 is a side elevation of the upper end portion of a door frameand door to which is applied a device embodying my invention, Fig. 2 isa horizontal section taken on substantially line .r-m of Fig. 1, Fig. 3is an enlarged sectional detail of the pivotal connection between thejointed bar included in the construction and the door, and Figs. 4: and5 are enlarged detail sections taken on lines 7 and 2-2 respectively ofFig. 2.

The preferred form of construction as illustrated in the drawingcomprises a door 1 which is hingedly secured at 2 in the usual doorframe 3. Said door and frame are connected by a bar 4 one end of whichis pivotally secured to the under side of the upper bar of the frame 3through the medium of a member 5, the opposite end of said bar beingpivotally connected at 6 with a plate 7 which is fastened to the innerside of the door adjacent the upperedge thereof.

Interposcd in thebar 4 is a plvotal joint 8 whereby, when the door is inclosed position said bar will fold together as shown in Fig. 2. \Vhenthe door is in open position as shown in dotted lines in Fig. 9., saidbar will be in extended position, the same being held or releasablylocked in this position and hence the door in open position by means ofa hook 9 pivotally secured to the bar 4. adjacent the joint 6, said hookmember being adapted to engage an eye 9 provided. at one end of theplate 7, as clearly shown in dotted lines in Fig. 2.

Arranged between the p1\'otal joint 6 and .the eye 9 is a hous ng 10 theouter end of said housing being slotted at 11 in order to accommodatethe adjacent portion of bar 4 when in extended position as clearly shownin Fig. 3. Loosely mounted in the housing 10 is a member 12 normallyheld at. its outer terminal of movement by a helical compres sion spring13. W'hen the bar 4 is in engagement with the slot 11 the former willdepress the member 12 against the influence of spring 13 and so thatupon release of said bar through disengagement. of hook 9, said member12 will press the adjacent section of bar 4 outwardly and thereby causeoutward breaking of the joint 8 in said bar. This is of adi-antage inthat without such provision it would be necessary to break the joint 8by hand and such a provision is of further ad ant-age in that itobviates the possibility of inward breaking of the joint 8 as will bereadily understood. The member 12 also serves as a bumper, as will beobserved, since it absorbs the shock which would otherwise be,

incidental to suddenly unfolding the bar a desire to avail myself ofsuch variations and modifications as come within the scope of theappended claims.

Having described my invention what I claim as new and desire to secureby Letters Patent is:

1. In a device of the class described, the combination with a door frameand a door swingingly mounted therein, of a bar having a pivotal jointintermediate its ends, one end of said bar being pivotally secured tosaid door, the opposite end of said bar being pivotally secured to thedoor frame; means for maintaining said bar in extended position to holdsaid door open; and means on said door for causing said joint to breakoutwardly when said bar is released, substantially as described.

2. In a device of the class described, the combination with a door frameand a door swingingly mounted therein, of a bar having a pivotal jointintermediate its ends, one end of said bar being pivotally secured tosaid door, the opposite ends of said bar being pivotally secured to thedoor frame; means for maintaining said bar in extended position to holdsaid door open; and spring compressed means on said door for causingsaid joint to break outwardly when said bar is released, substantiallyas described.

3. In a device of the class described, the combination with a door frameand a door swingingly mounted therein, of a bar having a ivotal jointintermediate its ends, one end of said bar being pivotally secured tosaid door, the opposite endsof said bar being pivotally secured to thedoor frame; means for maintaining said bar in extended position to holdsaid door open; and a spring compressed ,bumper on said door adapted tocontact with said bar when in extended position angl cause said joint tobreak outwardly when said bar is released, substantially as described.

- 4. In a device of the class described the combination with a doorframe and a door swingingly mounted therein, of a bar having a (pivotaljoint intermediate its ends, one en of said bar being pivotally securedto said door, the opposite. end of said bar being pivotally secured tothe door frame; a hook on said bar adapted for engagement with an eye onsaid door for maintaining said bar in extended position to hold saiddoor open; and a spring pressed bumper on said door adapted to contactwith said bar when in extended position and cause said joint to breakoutwardly when said bar is released, substantially as described.

5. In a device of the class described the combination with a door frameand a door swingingly mounted therein, of a bar having a pivotal jointintermediate its ends, one end of said bar being pivotally secured tosaid door, the opposite end of said bar being pivotally secured to thedoor frame;

a hook on said bar adapted for engagement with an eye on said door formaintaining said bar in extended position to hold said door open; ahousing on said door adjacent the point of connection therewith of saidbar; a spring compressed member in said housing, the upper end of saidhousing being slotted for receiving the adjacent portion of said barwhen in extended position, said bar, when in extended position, causingdepression of said spring compressed member and so'that when said dooris released said joint will be caused to break outwardly, substantiallyas described.

In testimony whereof I have signed my
